Turbo going bad?

[cthis79]

So, the other night my truck decided to be a little weird. When I started my truck the exhaust was super deep and throaty, but it's never sounded like that before. Then after about a minute of warming up it sounds like the turbo spools and my exhaust go back to normal.
I attached a video of what I'm talking about, anybody know what's going on? I'm thinking possibly wastegate. Thanks yall. Also, sorry about the quality of the video, had to take it on my phone.

When my turbo was going it would idle and be making 1 or 2 psi. I had sticking vanes in my turbo. It would be louder at idle but not deep like yours is at first. The only thing I can think of is possibly the sticking vanes.

Some strategies have a turbo vane sweep written into them at idle to keep the vanes from sticking. Does it still make normal boost on the highway? And btw 6.0's aren't wastegated.

Yeah, I normally run 10+lbs when just cruising and when I need to get on it she'll still make 20+lbs with no problem.

Take apart the turbo and clean the unisens wheel. I had that same problem.

I thought just normal cruising should be in the 3-5lb range?
